Benefits of technology

[0010]The above structure yields the following advantages. During the earthquake, the image formation is interrupted; this prevents the image forming apparatus from degrading image Duality due to a direct effect of an earthquake-induced vibration. Furthermore, after the earthquake is over, the image forming apparatus makes a registration adjustment prior to the image formation. This prevents color shifts resulting from the earthquake.
[0012]Here, it is desirable for the image forming apparatus to include a scanner for generating the image data by scanning an original, wherein the controller instructs the transmitter to transmit only the image data generated by the scanner to the another apparatus. This construction reduces the time needed to transmit the image data by reducing an amount of the data to be transmitted to the another apparatus. As a result, the transmission of the image data can be completed before it is disabled by the earthquake.
[0014]Here, it is desirable for the image forming apparatus to include an inquirer for submitting an inquiry to the another apparatus via the network about whether the another apparatus has detected vibration, wherein if the intensity of the vibration is judged by the image forming apparatus to be larger than the second threshold, the controller instructs the inquirer to submit the inquiry to the another apparatus about whether the another apparatus has detected the vibration, and if the another apparatus has not detected vibration, the controller instructs the transmitter to transmit the image data of the interrupted image formation to the another apparatus. This construction allows the image forming apparatus to transmit the image data to the another apparatus that is undamaged by the earthquake and thus is able to carry on the image formation safely. This way the image data can be more definitively transmitted to the another undamaged apparatus after the earthquake has ceased.

Problems solved by technology

Along with the widespread use of image forming apparatuses in recent years, there are increasing cases of them being hit by an earthquake.
However, there still remains a problem; following the earthquake, the restarted printing sequence does not always output a high-quality image.

(1) First Modification Example

[0063]In the above embodiment, the present invention has used 6 the vibration detector that measures the vibration intensity by compression of the piezoelectric element having the weight mounted on top thereof. The present invention, however, may instead use any other type of vibration detector.

[0064]The any other type of vibration detector includes a shear mode vibration detector. FIG. 8 is a cross-sectional view illustrating a main structure of a vibration detector of the present modification example. As shown in FIG. 8, the vibration detector 8 includes: a piezoelectric element 801; a weight 802; a base 803; and an amplifier 804.

[0065]The piezoelectric element 801 is comprised of a piezoelectric material 801a whose both ends in a polarization direction are attached to electrodes 801b and 801c. The weight 802 is attached to one side of the piezoelectric element 801 in a main direction. The piezoelectric element 801 and the weight 802 are placed within...

(2) Second Modification Example

[0068]The image stabilization process generically refers to a process for stabilizing an image to be printed. When characteristics of components and processing tasks (i.e., characteristics of a photoconductive drum and developing / charging characteristics) change due to environmental, durability and other reasons, a color and density of a printed image consequently change and the image thus becomes unstable. The image stabilization process restrains such changes and maintains the image stability. The image stabilization process includes: a marking laser intensity adjustment; a toner concentration adjustment; a gamma detection / adjustment; and a registration adjustment.

[0069]In the present invention, the image stabilization process preferably deals with components and processing tasks that are affected by the earthquake shaking. For example, when printing in color, the MFP 100 may develop a problem of color shift due to the earthquake shaking. To prevent ...
